CAUTION - ONLY CHARGE WITH A RECHARGEABLE,

LITHIUM BATTERY (LIR 2032) AND THE 110-VOLT(1) OR 230-VOLT(2) AC/DC TRANSFORMER PROVIDED. OTHER BATTERY AND TRANSFORMER WILL CAUSE INJUREY AND DAMAGE.

(1) For US only (Optional) (2) For European country

The watch must be fully charged before its initial use. When the watch displays ìLOW BATT.î (as shown in Figure 1) means the battery

in your watch need to be charged, please follow the below sequences to charge the battery:

Step 1: Use the Connector with one end clamp to the watch and the other end connect with the PC Interface and Charger (for EON3068HS) or Charger (for EON-3067HS). Make sure the three pins in the clamp are properly in contact with the three contacting points on the watch. (as shown in Figure 2 & 3)

Fig.2 Fig.3

Fig.1

LAP

Step 2: Use the supplied Transformer, one end connect with the PC Interface and Charger (for EON-3068HS) or Charger (for EON-3067HS),

the other end plug into a proper voltage AC wall outlet. When the light on the Charger turns from red to green, indicates the battery

is fully charged. (Note: For the purpose of watch only, the battery will last for

about 3 weeks. If you fully utilize the Fluid Loss and Heart Rate features (optional) for 1 hour everyday, the battery has to be re-charged for every week.)

Note:

1) The first time you try connecting the watch to the connector. Center the connector so that it is guided between the 2 mode buttons on the watch before it is fully inserted.

2) The bottom tab on the connector when properly inserted should be flush with the bottom of the watch. (as shown in Figure 3)

3) When the watch and connector are properly connected, the LED on the Charger will light up as red.

4) To achieve the best performance out of the watch battery, it is recommended to charge the watch for at least 12-hour before its initial use.

5) If you fully utilize the Fluid Loss and Heart Rate features for an average of 1hour a day, you are recommended to recharge the watch once a week. (For Time purpose only, the watch should last about 3 weeks.)

6) To ensure a longer period of the battery life, we recommend you to charge the battery immediately when the low-battery warning (i.e. "LOW BATT." ) appears on the watch.

7) After the first low battery warning comes on for 15 minutes, the EL, Heart Rate, Humidity & T emperature features will be turned of f in saving the battery energy.

8) When you charge the watch after it shut down, it will first enter Time & Calendar Setting Mode automatically, that enable you to adjust the time and calendar for the watch. After you finish the setting, it exits to the normal mode. Your personal settings and exercise data for your last exercise are well kept by the watch.

Part II

Getting to Know Fluid Loss

When exercising, your body regulates temperature through sweat loss, heat radiation and respiration. Dehydration reduces maximal aerobic power and endurance performance. Greater dehydration results with greater decrements in performance. The Fluid CheckTM feature provides

Part II

feedback to you with respect to your dehydration level. See page 88 for

Fluid CheckTM Monitoring Tips and Guidelines.

Fluid CheckTM feature is controlled by the stopwatch. If you have turned

on the Fluid CheckTM feature, the watch will show the fluid loss value in the Recall Data Mode. When in the Chrono Mode, the watch display will flash and the watch will beep each time your fluid loss equals .5% of your body weight. The higher the amount of fluid loss, the faster it will beep.

Tips:

1) If you did the Personal MET Calibration ( Optional ) and take the Transmitter Belt with you during exercise, the watch will calculate the amount of your fluid loss by detecting the physiological changes of your body ( see page 37 ) .

2) If you have no Transmitter Belt (or forgot take it with you), you would need to manually input Exercise Type & Intensity (see page 35).

Note: Unless the stopwatch is running, the Fluid CheckTM feature will

automatically turn off at the midnight (i.e. 12:00 PM).

LAP

Getting to know the three Target Zones (TZ)

In order to benefit the most from your workout, you need to become familiar with your Heart Rate Target Zone. For most people, as your heart rate exceeds the upper limit, your body begins to become anaerobic and produce acids. By working within the correct range, you will achieve your fitness goals and strengthen your cardiovascular system in less time.

Zone 1 (Fat Burning Zone, 55-65%) -This range is recommended for those who haven't worked out in a long time, are trying to lose weight, are at a high risk for heart problems or if you're just not feeling 100% one day.

Zone 2 (The Aerobic Zone, 65%-85%) - This range is recommended for those in good physical condition who have been exercising on a consistent basis for an extended period of time. Exercising at this range helps improve your fitness level and prevent injury caused from overtraining.

Zone 3 (The Anaerobic Zone, 85% - 95%) This range is used only for those in extremely good physical condition during races or training for competition. It is typically used for interval training to help improve or measure endurance levels.

Select Target Zone Before Exercise

Select a desired Target Zone before exercise. The watch will record the time you are In, Below and Above this Zone, the Average Heart Rate, and will give both visual & audible indications when you are out of the Zone during exercise.

Target Zone & Fitness Training

Target Zone & Fitness Training

Determining Your T arget Zone

What is Target Zone Heart Rate Training? In order to benefit the most from your workout, you need to become familiar with your heart rate training zone. By working within the correct range, you will achieve your fitness goals and strengthen your cardiovascular system in less time. Here is basically how it works.

Effective conditioning requires that you maintain your heart rate at the proper level for at least 20 minutes per workout (or per day). At too high of a heart rate your activity can become counter effective. For most people, as your heart rate exceeds 85% (the upper limit), your body begins to become anaerobic and produce acids. This also burns less fat which can begin to burn and strain muscles, and even start storing fat. As for the lower limit, this number tells you when you have reached a level of intensity that is productive. A heart monitor will tune you into your body's internal activity level and helps prevent injury or worse.

To make this part easy for you, the Hydra-AlertTM automatically sets the correct target zone for you after you enter in your age in the heart rate setup mode. The internal auto-setting is based on a generally accepted standard range of 65 to 85% of your maximum HR (where max HR = 207 - Age x 0.7).

There are many variations of formulas for calculating target zones. In most cases they will come up with a range very close to or the same as the autosetting of the Hydra-AlertTM. If you prefer to fine-tune or program your own limits, this can also be done in the HR Setting Mode (see page 43). The internal automatic TZ calculation is based on the following example:

Part III

TARGET ZONE CALCULATION FORMULA

207 - Your age x 0.7 = max HR

For a 30 year old person, your

calculations would be as follows:

207 - 30 X 0.7 = 186 Maximum Heart Rate

65% of this number = 121 85% of this number = 158

The calculated exercise range for a 30 year old would be a low of 121 and a high of 158 beats per minute. (You should never exercise near your maximum heart rate (max HR) for any period of time.)

Basic Fitness Tips & Target Zone

Part III

Depending on your specific goals, individual fitness level or just on how energetic you feel, you may want to modify your range from one day to the next based on the following chart:

or Less

Stretching

Begin and end every workout with stretching. Stretching done before your workout increases flexibility to help prevent muscle strain or injury and stretching after, loosens tight muscles and helps prevent soreness. Stretch before warm up & after cool down. Stretch slowly & gently, never bounce or stretch to a point of pain. Hold each stretch 30-60 sec. & exhale as you extend stretches.

Warm Up & Cool Down: 55% or Less

Start every exercise with a slow and gradual warm up and end with a slow and gradual cool down. Smoothly easing into and out of strenuous activity helps your body prepare your metabolism and blood flow to efficiently break down fat and change over from one intensity level to another. Going into your target zone too quickly can cause your heart rate to increase too rapidly causing you to loose your energy too soon, strain yourself or possibly worse. Slowly bring your heart rate to a level just below the lower limit of your target zone. Maintain heart rate at this level for 5-10 min.

The Fat Burning Zone: 55- 65%

The Fat Burning Zone: 55-65% --This range is recommended for those who haven't worked out in a long time, are trying to loose weight, those at a high risk for heart problems or if youíre just not feeling 100% one day. It is intended for low intensity and/or long duration exercise. The lower intensity helps you maintain your exercise for longer periods of time. When exercising for weight loss or starting a new exercise routine, longer duration is more important and much healthier than higher intensity. Build up gradually to 30 to 60 min. per workout. Workout 3 or 4 times per week.

Part III

The Aerobic Zone: 65- 85%

This range is recommended for those in good physical condition who have been exercising on a consistent basis for an extended period of time. Exercising at this range helps improve your fitness level and prevent injury caused from over training. Duration: 20-30 min. per workout. Frequency: At least 3 or 4 times per week.

The Anaerobic Zone: 85% to Max HR

Part III

To be used by ultra-athletes only and never recommended without close medical approval or supervision. This range is used only for those in extremely good physical condition during races or training for competition. It is typically used for interval training (or short sprints) to help improve or measure endurance levels.

Monitor Your Progress

Track yourself to determine how your overall health and fitness improves and become aware of your various heart rate levels. As your cardiovascular system improves, your normal resting heart rate will decrease. It will take longer to reach your target zone, it will take less and less time for your heart rate to come back down after working out.

If you ever notice your resting heart rate to be higher than usual, it may be a good idea to take a rest from exercise, or at least workout easier that day, Similarly, if you notice that your heart rate doesnít come back down as quickly as usual at the end of your workout, it could be an indication that your workout was more (or too) strenuous, or that you havenít recovered well enough from a previous extraneous workout or injury. These signals in your heart rate could also be an indication of an illness coming on, stress, or a good reason for a check up with your doctor.

Getting to Know

Heat Index

Getting to Know Heat Index

High humidity makes heat more dangerous because it slows the evaporation of perspiration-the body's natural cooler. That caused outdoor exercise more dangerous even for those in good shape.

Key rules for coping with heat are to drink plenty of water to avoid dehydration and to slow down and cool off. Overheating can cause serious, even life-threatening conditions such as heat stroke.

Part III

The Heat Index is to show how hot a particular combination of heat and humidity feels. The Heat Index in the Hydra-AlertTM is a report of the latest weather conditions based on the current temperature and the relative humidity. You can refer to the following Heat Index Chart to know the apparent temperature and to avoid getting into danger during exercise.

Body Fluid Check Monitoring Tips and Guidelines

Body Fluid CheckTM Monitoring Tips and Guidelines

The ACUMEN Hydra-AlertTM provides an indication of the level of dehydration. The purpose of the dehydration reading is to remind an individual to drink fluids.

It takes the human body 12 to 24 hours to replace fluids from heat and exercise. To prevent the harmful effect of excessive dehydration it is necessary to drink before you become thirsty.

The thirst mechanism is not precise in humans. An individual can lose fluids equaling up to 3% of their body weight before the thirst mechanism tells the person they need fluids.

Strength and endurance are reduced by 10-15% after just a 2% loss of body weight, through dehydration.

Most people need more than eight ounce glasses of water per day. The water intake each day needs to be half your body weight in ounces. Do not drink over 32 ounces at any one time. Do not consume more than four ounce glasses of water in any one hour period. Divide the water intake over the entire day.

If the exercise period is under 60 to 90 minutes water is always appropriate. If the exercise period is more than 60 to 90 minutes, a sports drink offers an energy advantage that can enhance stamina and endurance.

Part III

Cardiac drift occurs because dehydration causes a drop in blood volume with less blood being pumped with each heartbeat. The heart rate increases 7 beats per minute for each 1% loss in body weight due to dehydration.

The keys to Proper Hydration: Drink on schedule, rather than relying on thirst Drink during training as well as competition Drink cold water to increase gastric emptying

Part III

The opinion of the American College of Sports Medicine on Exercise and Fluid Replacement (ACSM, 1996) is that adequate fluid replacement helps maintain hydration and, therefore promotes the health, safety and optimal physical performance of individuals participating in regular physical activity.

Use of the dehydration indicator on the ACUMEN Hydra-AlertTM will help an individual develop a regimen to maintain appropriate levels of hydration.

Precautions, Warranty, Service

and Repair

General Precautions

Do not operate buttons under water

Although your monitor is water resistant, be sure that you do not operate the buttons under water as pressure can cause them to leak.

Dry off watch after use

Moisture can affect the Temperature and Heat Index reading. Please dry off your watch after use.

Dry off transmitter after use (Optional)

The transmitter will automatically shut itself off once you have removed it from your chest. However, it is important to thoroughly dry it off after every use since moisture on the electrodes can cause it to remain on longer.

Part IV

Electrode precautions (Optional)

Be sure not to excessively twist or bend the electrode portions of the chest transmitter (never bend backwards), especially when storing it. This can permanently damage their conductivity and cause mechanical damage to the internal circuit.

Global Reset

If your monitor should ever get stuck or act erratically due to dropping it, static shock or some other unforeseen reason, this feature will allow you to reset the unit and return all settings back to their internal defaults. To perform this function, press and hold four buttons together for 3 seconds under any mode (display dual LCD). The unit will automatically clear and return to setting mode.
